Renald Luzier also known by his alias, Luz, who is the Charlie Hebdo cartoonist that designed the front page of the magazine that appeared after the Paris attacks, has said he will no longer draw the Prophet Muhammad.

"I've got tired of [drawing Muhammad], just like I got tired of drawing Sarkozy. I'm not going to spend my life drawing them"

BBC reports that Luz is about to release a book of cartoons entitled "Catharsis", which he says in his interview was his way of expressing himself after the murder of his colleagues.

It would be recalled that on 7th January, 12 people were murdered when 2 Islamist gunmen burst into the Charlie Hebdo offices. The attack prompted a wave of sympathy under the banner "Je suis Charlie".

Within days of the attack, the satirical magazine's surviving staff produced a defiant edition with the headline "All is forgiven" above Luz's cartoon showing the Prophet weeping, while holding a sign saying "I am Charlie".

The event marked a turnaround for the magazine and its now gone from regularly struggling to making ends meet to being backed up by tens of millions of euros of funding.

But Luz says that financial security has posed questions about its future editorial direction and in February, former Charlie Hebdo editor Philippe Val said he feared for the magazine's survival amid a new media climate of self-censorship.
